GENERAL DESCRIPTION

The ADL5323 is a high linearity GaAs driver amplifier that is

internally matched to 50 Ω for operation in the 1700 MHz to

2400 MHz frequency range. The amplifier, which has a gain of

20 dB, has been specially designed for use in the output stage of

a cellular base station radio or as an input preamplifier in a

multicarrier base station power amplifier. Matching and biasing

are all on-chip. The ADL5323 is available in a Pb-free, 3 mm ×

3 mm, 8-lead LFCSP with an operating temperature of

−40°C to +85°C.
